简介：塑造耳朵的热前面(ESTF)，由黄海温暖的水流(YSWC)和山东沿海的水流(SCC)的集中形成了，在冬季是在黄海(YS)的很重要的海洋的现象。在所有表明的situ大小和分析数据集，ESTF在1950s-1990s，和一个类似的变弱趋势期间一直在变弱，这是也在YS上在冬季季风发现。数字实验证明变弱冬季季风能沿着瓷器海岸和向南方的异常水流与向北方异常的水流在多十的timescale上在YS导致异常发行量在里面中央对季节的吝啬的循环YSgenerally相反。异常发行量引起YSWC和SCC的减速，并且因此削弱ESTF。因为ESTF在地区性的海洋动力学和由空至海的相互作用起重要作用，它变弱在冬季在YS为地区性的气候有重要含意。
